TV Antenna Repairs & Extra Points

Most antenna repairs in Sydney turn out not to be antenna problems. The aerial is the part you can see, so it gets the blame, and on the majority of call-outs it is mechanically sound. The fault is underneath it: a connector that has sat in the weather for a decade, a splitter feeding more outlets than the signal can carry, or coax that was run before digital television existed.

Ray Anjoul has run Creative Sound & Vision since 1994 and goes to every job himself. He came to antennas from forty years in audio engineering, mixing for touring artists and festivals, which is work built entirely on finding where a signal falls apart between the source and the room. A rooftop aerial is the same problem with worse weather.

What actually causes a picture to break up

Almost every reception fault in Sydney is one of five things, and none of them is the television. Knowing which one it is before anybody climbs a ladder is most of the job, and it is why the meter comes out before the toolbox.

A corroded connector

The most common fault by a distance, and the cheapest to fix. The F-connector at the mast sits in the weather for a decade; water gets into the braid, the shield corrodes, and the signal drops a few dB every winter until one wet night it falls below what the tuner can decode.

Too many splitters

Every split costs signal. A two-way splitter takes about 3.5 dB, a four-way about 7 dB, an eight-way more than 10 dB. A house that was fine on two TVs and started breaking up when a third and fourth point went in has not developed a fault. It has run out of signal to share.

Amplification in the wrong place

An amplifier in the lounge boosts the noise along with the signal, because by then the damage is done. Amplification belongs at the masthead, before the losses, and only where the incoming signal is genuinely weak. Close to Artarmon an amplifier usually makes reception worse, not better.

The antenna itself

Elements bent by a storm, a mast that has rotated a few degrees, or a balun that has finally let go. Ten to fifteen years is a normal life inland and less near the water, so on an older house this is a real possibility rather than an upsell.

Old cable

Pre-digital coax was never made for these frequencies. If the cable in your roof is the thin black stuff with a single braid, it is leaking signal along its whole length and no antenna will fix that.

What a repair visit actually involves

Signal is read at the antenna first, then again at every outlet in the house. Those two numbers are the diagnosis between them. Strong on the roof and weak at the wall plate means the aerial was never the problem, and replacing it would have fixed nothing. Most visits end with a connector re-terminated, a splitter swapped for one the house can actually afford, or a run of old cable replaced, and the picture back the same afternoon.

That distinction is worth money, because a repair and a replacement are nowhere near each other in price. An aerial that is sound and correctly aimed does not need replacing because a connector has corroded. Where the antenna genuinely is finished, and fifteen years near the water will do it, you get told so with the meter reading that shows it.

Extra antenna points, without lifting your floor

A new outlet in a bedroom or a study is usually run from the roof cavity down inside the wall, which means no chasing, no patching and no floorboards up. Where a wall cannot be dropped (double brick, or a downstairs room with a floor above it), the run goes in a slim duct that gets painted to match, or externally along a fascia and back in behind the TV. We will tell you which of those your house is before quoting, not after starting.

If the house is already at its signal limit, an extra point is the moment that shows up. That is a distribution amplifier rather than a bigger antenna, and it is worth doing at the same visit rather than discovering it a fortnight later.
